Star Polymers: An Overview
نویسندگان
چکیده
This review article describes the synthesis, properties and some applications of star-shaped polymers. The arms constituted of homoor co-polymers of different polymers are also reviewed. Methods of synthesis of various types of starshaped polymers, including “arm first” and “core first” procedures, is given as an introduction along with some details. Then, the synthesis of star polymers (including miktoarm stars) with strictly defined as well as with varying number of arms and having cores formed from small and/or large molecules: branched, cross-linked, etc., is described. Interest in star-shaped and branched systems based on poly (ethylene oxide) (PEO) is mainly motivated by their potential applications in the biomedical and pharmaceutical areas. The properties and applications of PEO stars are also reported, such as drug carriers, surface modifiers, hydrogels, components of membranes, and also have some biomedical applications. Their potential applications as components of different types of complexes, hydrogels, networks, and ultrathin coatings are indicated.

A short review on Ferrofluids surface modification by natural and biocompatible polymers
This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

متن کاملDramatic Morphology Control in the Fabrication of Porous Polymer Films
Highly ordered, porous honeycomb films are prepared by the breath-figure (BF) technique using dendron-functionalized star polymers as precursors. By changing the nature of the dendritic end groups, dramatically different porous morphologies can be produced. Three series of star polymers are prepared with both the size of the 2,2-bis(methoxy)propionic acid (bis-MPA)-based dendron end group and t...
متن کاملEfficient and versatile synthesis of star polymers in water and their use as emulsifiers.
Core cross-linked star polymers of low polydispersity were efficiently prepared in high yield by RAFT-mediated emulsion and dispersion polymerizations in water at high solid content. These star polymers were demonstrated to be effective emulsifiers, and the emulsion was successfully used as template to fabricate polymer particles.
